There is growing evidence indicating that dihydroaustrasulfone alcohol inhibits cell migration in human non-small cell lung cancer A549 cells and endothelial cells by inhibiting the activities and expression of matrix metalloproteinase (MMP)-2 and MMP-9, thereby suppressing lung cancer cell growth and angiogenesis [12,36]. The gene discussed is MMP9; the disease is non-small cell lung carcinoma.
